CHARLES BORGESON, OF PITTSBURG, PENNSYLVANIA.

WRENCH.

SPECIFICATION forming' part of Letters Patent N0. 671,789, dated April9, 1901.

Application filed July 28.1900. Serial No. 25,080. (No model.)

To @ZZ whom it may concern/.-

Be it known that I, CHARLES BoRGEsoN, a citizen of the United States ofAmerica, re-

siding at Pittsburg, in the county of Allef scription thereof, referencebeing had to the accompanying drawings, which form a part of thisspecification.

This invention relates to certain new and useful improvements inwrenches, and has for its object the provision of novel means wherebythe wrench will be automatically disenl gaged from the nut, shaft, orsquare ends requiring a wrench for adjustment.

The invention has for its further object to construct a wrench of theabove-described character that will contain comparatively few parts thatare not liable to become out of order and when broken may be easilyreplaced.

The herein described invention further aims to construct a device ofthis character that will be extremely simple in its construction,strong, durable, and comparatively inexpensive to manufacture;furthermore, one that will be highly efficient in its operation.

With the above and other objects in view my invention finally consistsin the novel construction, combination, and arrangement of parts to behereinafter more particularly described, and specifically pointed out inthe claims.

In describing the invention in detail reference is had to theaccompanying drawings, forming a part of this specification, and whereinlike numerals of reference indicate like parts throughout the severalviews, in which- Figure 1 is a perspective view of my improved wrench.Fig. 2 is an enlarged longitudinal vertical sectional view of the loweror engaging end of the wrench. Fig. 3 is an end view of the wrench asshown in Fig. 2.

In t-he drawings the reference-numeral 1 indicates the body portion ofthe wrench; 2, the handle thereof. 4 indicates the lower enlargedcylindrical portion of the same, the latter being provided with a squarechamber 5 and outwardly-extending guideways 6, arranged diametricallyopposite each other.

The referen ce-numeral 7 indicates a spring` pressed follower havingarranged on its rear face a shank 7a. The said follower is furtherprovided with guides 8, adapted to register with and operate in theguideways 6. A spiral spring 9 is arranged within the chamber 5, havingits one end secured to the shank '7a of the follower and its other endfastened to a lug l0, extending into the chamber 5, by means of a pinll, the latter passing through suitable apertures formed in the enlargedcylindrical portion and the lug.

The parts when assembled are arranged in such'a manner that the followerwill almost be iush with the end of the enlarged cylindrical portionwhen the spring is in an exi panded position.

The operation of the device is as follows: The square end of the wrenchbeing adapted to engage the part to-be adj usted in the usual manner, aslight pressure being exerted, thereby depressing the spiral spring andforcing the follower into the chamber, the guides riding in theguideways rearwardly until the pressure is released, when the followerwill be forced to its normal position by the expansion of the spiralspring, which will tend to automatically free the object from engagementwith the wrench.

It will be understood that the chamber and engaging end of my wrench,although shown as square for the purpose of illustrating my invention,may also be made in the shape of ahexagon, Octagon, or any other desiredform and that any convenient form of handle may be adopted and thatother minor changes in the construction may be made without de partingfrom the general spirit of my invention.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is- Y l; As an improved article ofmanufacture, a socket-wrench consisting of a body portion havingformedtheren a chamber and guideways, and provided with aspring-actuated follower and guides for operating in said guideways,substantially as specified.

2. A device of the character described, consisting of 4a suitablehandle, a body portion having formed therein a chamber and guide- IOOways, a follower carrying guides adapted to In testimony whereof I havehereunto afoperate in said gui'deways, a spiral spring ar- Xed mysignature in the presence of two sub- 1o ranged within said chamberhaving its one soribing Witnesses.
